Burglary doors: features of choice

The main task of the front door is to protect the home from burglary, so it must be made of high quality materials using a special technology. In order to choose the best option, you need to familiarize yourself with all the features of anti-burglary structures. Knowing all the nuances of the right choice, you can secure the house to the maximum.

The front door is the shield of the house, so it must have a number of properties. In order to have a stable and solid base, it should consist of a steel multilayer face plate, a reinforced frame, an armored locking structure and a monolithic triplex in a glass block with a reinforced reinforced grid. There must be a non-combustible and heat-insulating filler inside the canvas.

Entrance anti-burglary panels should prevent burglary by sawing hinges or opening with a crowbar. They must be resistant to mechanical damage, up to shots from firearms or detonation. Even when towing a small truck, the door must resist pressure and stay in place.

The anti-burglar structure cannot be jacked, sawed with an electric saw or perforated. Even flame welding should be powerless in the way of burglars getting inside the house. Of course, according to research, any door can be opened, but a high-quality canvas should withstand burglary as long as possible. During the time that intruders will fiddle with the locks, someone may notice them and call the police.

Burglar-proof entrance panels are not always installed by rich people who are most worried about their property. They are very often purchased for financial institutions, museums and office institutions. And the average citizen is interested in his own protection, so he often pays attention to just such constructions.

Burglary-resistant canvases are soundproofed and have low thermal conductivity. They are equipped with high-quality door fittings, which are designed for multiple opening and closing. A wide range of products allows you to choose an interesting design that will decorate the facade of the house.

Anti-burglary structures should be selected taking into account their classification. To protect the home, experts recommend purchasing class 2 or 3 products. Class 1 doors are considered to be the weakest in terms of stability, and they are usually placed at the entrance to internal premises.

On the 2nd class there are blocking devices and reliable locks, which allows you to protect the building from burglary. Even experienced craftsmen cannot always cope with such a task. The most reliable panels are class 3. They are equipped with crab and multi-nail locks, and locking pins increase the stability of the door frame. But such serious designs are not easy to find in a door store, since they are generally made to order in a single copy.

There are also 4 and 6 classes of burglary resistance. They differ in that a class 4 door is capable of withstanding an assault rifle fire, and a class 6 product can withstand a rifle shot. Burglary resistance of the structure implies full compliance with international standards and certification.In order to open it, it must take at least 10 minutes, and if it has grade 4, then at least half an hour.

The peculiarity of choosing such a specific door structure is the selection of not only a stable, but also a multifunctional option. An armored panel must have a proprietary lock that is resistant not only to opening, but also to making a cast. There must be an optical eye and a protective chain inside the canvas. Doorknobs and hinges must be strong enough to be resistant to sawing or other mechanical stress.

Most people, when buying an anti-burglar entrance structure, are guided by the thickness of the metal that makes up the door panel. Following a logical opinion, initially it seems that the thicker the metal, the stronger and stronger it is. A massive door inspires confidence, but in fact, such a product is not always highly resistant to burglary.

The peculiarity of the door leaf with an anti-burglar system is that there is no clear dependence of the thickness of the metal on the quality of the product. If the metal sheet has a thickness of more than 3 mm, it can be assumed with a high probability that a low-quality material was used for its manufacture. This is due to the fact that in order to increase the stiffness of the blade, it is necessary to provide a greater thickness of the metal.

Burglary-resistant door products are distinguished by a complex structure, which, with a certain calculation, must strengthen the strength with the help of a special system of internal reinforcing ribs. Many technical ideas are aimed at reliably resisting the door to any type of burglary, even if it does not have external metal sheets. Such a product is expensive, since a special complex technology is used for its manufacture.

Today, on the building materials market, you can buy door structures, the metal thickness of which is 0.8-1.2 mm. In this case, most of it falls on the paintwork. Such a sheet is very soft and unstable, and therefore does not have resistance to opening. When purchasing such a door, you should not expect that it will be able to withstand the load more than an ordinary wooden structure.

In the production of burglar-resistant panels, hot-rolled or cold-rolled metal can be used. For the manufacture of cold rolled sheet, high quality steel is used, while for hot rolled sheet, low quality raw materials are used. Therefore, hot-rolled steel doors are heavy and thick, but do not have good performance characteristics.

The cold-rolled production method is good in that it provides for complete descaling. It is almost impossible to do this manually, therefore, they resort to special technology in production. Additional cold rolling of the steel provides the sheet with additional rigidity and strength. It has the ability to bend without cracking, and there are practically no irregularities.

Before you go to the door store and purchase your favorite model, it makes sense to study customer reviews on thematic forums. The quality of burglar-resistant doors is discussed not only by users, but also by the manufacturers themselves.

After carefully reading the opinions of Internet users, you can consciously come to your own decision:

• People who prefer products made from hot-rolled raw materials emphasize their availability. Manufacturers of such products are trying to save money and purchase low-quality metal, which is made using welding technology. Therefore, the installation of such a model will be no different from the purchase of an ordinary wooden door.
• It is best to give preference to cold rolled steel models, as they have a number of advantages. They have a flat surface and uniform thickness, and they also have no residual stress. Such doors cannot be broken or damaged. And due to the absence of scale, they are not susceptible to corrosion.

• The thickness of the metal sheet at the selected door should be 1.2-1.5 mm. Such a panel will be lightweight and affordable.
• It is especially important to pay attention to the manufacturer when buying an anti-burglar construction. If he is little known, then perhaps he uses low-quality materials in production. Therefore, it is also important to check all its accompanying documents.
• In addition to its operational properties, an entrance or interior door should have an aesthetic appearance. The modern market offers a wide range of models with a variety of designs. When deciding to buy a certain canvas, you need to focus on the overall style of the facade of the house.
• If, when choosing an entrance door, the buyer has questions, then you need to contact a consultant who will tell you about all the advantages of the presented models.
